I'm getting really annoyed with the rain. I don't have a garage and my Z is sat on our drive, the problem i have got is that I want to put my hardtop on anytime now. I put my car cover on last week when the rain came down really hard. Now my roof has a green mouldy tint to it and I don't know whats best for the roof as i need to clean it but just can't get it dry because of the bloody rain. Has anyone else got the same problem and is their any valeters in the bolton area(I don't mind travelling) that can clean/waterproof the roof and dry it out so that i can put the hardtop straight on?

You can use a good quality roof cleaner / proofer (such as autoglym c£20) to clean (which will remove the mold) and proof whilst it is still damp.

You could try buying some of the moisture absorbing pouches to leave in the rear roof compartment before you lower the roof (and also under both seats,I always do this with a convertable).

This would help absorb any dampness but as you say you need a few hours break in the rain to get dry enough to lower for the long term hardtop fitting. You should only need a few hours though, use a large cotton (eg towel) to absorb as much moisture as you can so it will dry quicker

i've had my z3 for 5 years and never seen the rain this bad all the time i've had it. I was just a bit worried if i lower the soft top whilst still a little damp, then come to take the hardtop off next year and the softtop being covered in really bad mould. What are/where do you get the moisture absorbing pouches from?
